I live in an older walkup apartment with (I think) concrete floors and concrete block walls between units and the hallway (at least, when I once tried mounting something to one of those walls, I rapidly discovered that there was concrete behind the drywall. Either my neighbours are all very quiet, or it's quite effective at blocking sound transmission. Occasionally I'll hear music or TV noise in the hallway, but never in my apartment.
